Release notes Notes

Security

The Santa codebase has been undergoing dedicated security review by folks with access to frontier AI security models. The issues fixed below were identified through that work, and we recommend updating. This is an ongoing investment to ensure Santa remains your most trusted endpoint security solution.

Fixed additional ways a cached execution decision could be reused after an executable's contents changed
Fixed issues where a decision for one architecture of a universal binary could be applied to another architecture in the same file
Fixed an issue where a Touch ID approval for one architecture of a universal binary let another architecture that also required Touch ID run without a prompt during the approval cooldown
Fixed a race where an allow decision could still be cached by macOS after Santa had invalidated it
Fixed two issues where a local user could crash santad, pausing enforcement until it restarted

Full details for each issue are available in the published advisories.

Fixed

? Fixed transitive rules sometimes not being created when a compiler's output replaced an existing file, such as when rebuilding a binary in place
? Fixed unbounded memory growth when a block dialog was not shown, such as when the user had silenced it
? File access events once again report signing IDs with their team ID or platform: prefix, matching execution events. This had been broken since 2026.4.
? Workshop customers: With BlockNetworkMount enabled, Santa no longer blocks the macOS automounter's own mounts (such as auto_home and -hosts). Any network share the automounter then mounts is still checked against AllowedNetworkMountHosts.
? Workshop customers: Signal match reports now apply TelemetryFilterExpressions, so process...
